The Manager's Guide to Competitive Intelligence by John J. McGonagle, Carolyn M. Vella { Repost }

There is very little material available that provides practical, hands-on assistance for the CI professional who is providing CI to one client--his or her employer--and who constitutes the largest single group of CI practitioners in existence. This book meets that need by serving as a desk reference for CI managers to help them understand their own circumstances and determine what works best for them.
